PRESERVING- JAR.

Application filed September 29, 1923. Serial No. 665,630.

To all whom it filza-y concer/1t.'

Be it know that I, FREDERICK V. VIN'rnns,

a citizen of the United States, residing at `New York, in the county and State of New York, have invented certain new and useful improvements in Preserving Jars, of which the following is a tull, clear, and exact speci- L'ication.

This invention relates to preserving jars,

and has for its object to provide a. jar of improved construction which is especially adapted for use in connection with the vacuum preserving device disclosed in my companion application tiled herewith. i special object of the invention is to provide a preserving jar having smooth, cylindrical, external walls adapting it to be used with said vacuum preserving device without danger of the vacuum being destroyed. Another special object is to provide a ar with means for detachably interlocking' it to a portion of said vacuum preserving device.

Still another object is to provide the jar with a closure or cover capable of effecting an air tight closure therewith. Said cover is provided with a passage therethrough in which a sealing plug is placed so that air may be admitted to the jar by penetrating said sealing plug with a suitable instrument when the cover is to be removed.

Another object is to ormthe jar with a bottom and a correspondingly shaped top, so that a plurality ot the jars may be stacked tier upon tier with the recessed bottoni oit each fitting over the top of the next one below it and the stack thus maintained in proper vertical alinement and the danger ot' the upper tiers of jars falling oit being thus avoided. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part ot this speciiication, and then more specifically deined in the claims at the end oi the description.

In the accompanying drawings Figure 1 is an elevation of the jar constructed substantially in accordance with this invention.

Figure 2 is a bottom plan of the jar.

Figure 3 is a central vertical section thereot with the cover removed.

Figure 4 is a sectional view of the cover showing the passage therethrough without the sealing plug.

Figure 5 is a sectional view of the top portion of the jar with the cover seated thereon and the sealing plug arranged in the passage through said cover, and

Figure 6 is a fragmentary elevation ot the upper portion ot one jar and a section of the bottom portion oi another jar superimposed thereon, showing` how the jars may be stacked upon one another.

rlhe jar l is formed with smooth, cylindrical, external walls for the purpose already explained, and has an annular groove 2 near its bottom and spaced notches 3 leading from said bottom to said groove tor receiving the locking means disclosed in my companion application above mentioned. The top of the jar` is flat but the edge portion thereof is rounded off at 4l. The bottom of the jar is formed with a recess 5 corresponding to the shape ot the top, so that when a plurality of the ars are stacked upon one another, the recessed'bottom of each jar will tit over the top ot the next one below it, as illustrated in Figure 6.

ln the top of the jar there is a. stepped opening 6 to receive a similarly stepped cover or closure 7. A gasket 8 is interposed between the stepped portion oi the jar opening and cover Jfor eii'ecting an air tight joint between them. The cover and jar are preterably made oi' glass, butother suitable material may be employed in their manufacture if desired.

rThe cover has a stepped passage 9 therethrough, and seated on the step ot said passage is a sealing plug l0, Figure 5, of wax or other suitable material which serves to normally exclude air from the jar when the cover is seated thereon. lt will be noted that when the cover is seated, its top surface and the top surface of the sealing plug are flush with the top of the ar.

When it is desired to remove the cover from the jar, the sealing plug l0 is pierced by any suitable pointed instrument so as to permit air to enter into the interior oi the j ar. As soon as the vacuum in the jar has thus been destroyed and the atmospheric pressure within the jar has been equalized with that on the outside thereoi, the cover may be easily raised by the pointed instrument (not shown) or any other suitable means.

I claim:

l. A preserving jar having an external annular groove in its side wall near its base and vertical notches leading from its base to said groove for the purpose specified, a cover for said jar having a passage therethrough, and a sealing plug arranged in said passage in the cover.

2. A preserving jar having smooth, cylindrical, outer walls, a flatvtop with its marginal edge rounded off, and a recessed bottom corresponding to the shape of the top` marginal edo'e rounded ofi? and; a recessedbottom corresponding to the shape of said top, whereby a plurality of jars may be stacked. one'upon another with the recessed bottom oi' each fitting over the top of the next one below ita cover for'said ar having its upper face flush with the top of the and a passage extending through it, and a sealing plug in said passage with its upper face also fiush with the top of the jar.

4. A preserving jar having smooth,cylin drical, exterior walls, a flat top having its marginal edge rounded ofi", and a recessed bottom corresponding to the shape of said top, whereby a plurality of jars may be stacked one upon another with the recessed bottom of each fitting over the top of the next one below it, a cover for said jar having its upper face f'lush with the top of the jar and a passage extending through it, a sealing plug in said passages with its upper face also flush with the top vof the jar, there being an external annular groove in the lower portion of theside of the jar, and vertical notches extendingl from thee base of the jar to said groove for the purpose specified.

5. A preserving jar having smooth, cylindrical, outer walls, external annulargroove in its side wall near its base, and vertical notches leading from its base to said groove for the purpose specified.`

In testimony whereof I have signed. my naine to this specification.

FREDERICK V. IVINTERS.
